GAGE.

Application filed February 10, 1919.

To all "LU/lO/it it may concern Be it known that l, Josnri-r Bliosn, acitizen of the United States of America, and resident of lVheeiing,county of Ohio, and State or ll est Virginia, have invented certain newand useful Improvements in Gages, of which the following is a speciiication.

This invention relates broadly to gages, and more particularly to a gagefor carpenters use in laying outhinge mortises in doors.

The primary objector the invention is to provide an extremely simple andinexpensive tool which is adapted to be applied to the edge or a door orto the face of a door janib, and which, when so applied, presents edgesin position to followed with a scribing-awl or other pointed instrumentfor accurately marking the outlines to be followed in cutting a hingemortise.

A. further object is to provide a tool of the character mentionedadapted to be employed for simultaneously indicating the length, widthand depth oi the mortise to be formed, so that all necessary outlinesmay be marked by a single operation, or without moving or changing theposition of the tool.

A further object is to provide a tool which may be firmly andconveniently held in position with one hand while employing the otherhand to mark the outlines.

And a still further object within the contemplation of the invention isto provide a gage of the character mentioned which also serves as a gageby means of which a doorcasing may be accurately set or positioned withrespect to the door-jamb.

In describing the invention in detail, reference is herein had to theaccompanying drawings, in which- Figure 1 is an end elevation of theinvention; V

Fig. 2 is a perspective view of the same applied in operative positionto the edge of a door; and

Fig. 3 is a perspective view illustrating the application of the deviceas a gage for setting adoor-casin Referring to said drawings, in whichlike designating characters distinguish like parts throughout theseveral views- 1 indicates the main body portion of the device, the sameconsisting of a'thin flat plate of metal of rectangular form whichSpecification of Letters latent.

has a length corresponding to that of the hinge-leaf for the receptionoi which. the mortise is to be formed in the edge oi a door, as 2. Onoor the lateral edges of said plate 1 is turned at right an les to theplate, "forming a longitudinally extending lateral flange 3 the width ofwhich corresponds with the thickness or said hinge-leaf and,consequently, with the depth of the mortise to be formed. The width ofthe plate from the inner face or the flange 3 to the opposite lateraledge of the plate corresponds with the width of the mortise to betermed.

Carried on the outer face. of the plate 1, preferably in a centralposition, is a knob eiby means or which the device may be held in placewhile a scribing-awl or other pointed instrument is being passed aroundthe edges of the device to mark the outlines of the latter for visuallyindicating the boundaries of the mortise to be formed. The preferredtorn: oif knob is de icted in he drawings, the same consisting oi acyindrical shank or neck-portion 4r, an interal reduced stem i at theinner end of "itlCl shank disposed in threaded relation to the plate 1,and an integral enlarged outer w Go end or head portion 4: with inwardlyinclined or curved surface walls meeting and mergnig wlth those of saidshank or neckportion 4. In practice, said shank or neckportion is heldbetween the first and second fingers of a hand of the user, with thebacks or" said fingers resting upon the plate 1 and with the ball of thethumb of said hand resting in a shallow concave seat or socket 4provided therefor in the outer face of said knob. As is obvious,an'extremely convenient means of holding the device firmly in operativeposition is afforded by the form of knob described. I

To adapt the tool for. use as a gage for accurately settingdoor-casings, two or more stops or posts 5 are mounted on the outer faceof the plate 1 in a line parallel to that lateral edge of the platewhich is opposite the flange 3 and at a distance from said edge equal tothe distance (ordinarily about five-sixteenths of an inch) which it isdesired shall intervene between the inner edge 6 of the door-casing 6and the face of the door-jamb 7. In applying the tool to this use theouter face of the plate 1 is set against the edgeof the door jamb 7 withthe posts 5 resting firmly against the face of said jamb, as shown inFig. 3.

lVith the device held in this position, the door-casing 6 may be set inplace with its edge 6 abutting the edge of said plate, or said edge maybe employed as a straight edge for marking on the edge of the jamb theline to which the casing is to be set.

Fronirthe foregoing it Will be understood that the device constitutes avery simple, cheap and convenient tool for carpenters use, adapted bothfor gaging hinge-inortises and for gaging the setting 05!? door-casings.

W hat is clainied is l. A gage comprising a rectangularplate whichconstitutes a straight edge for marking the outlines of a hinge mortise,said plate having an inwardly directed right angle flange along one ofits lateral edges auapteu to form a depth gage for such inortisc, andmeans carried upon the outer face 1 of said plate parallel to and at aspaced from distance from the unfianged edge of said plate to form adoor casing gage.

plate having an inwardly directed right 7 angle flange along one of itslateral edges adaptedto form a depth gage for such mo1= tise,a'pliirality of stops rigidly carried in alined relation upon the outerface of said plate parallel to and at a spaced distance the unfiangededge of said plat-etc form a door casing gage.

In testimony whereof, I. aiiix my signature in presence of twosubscribing Witnesses.
